We know, drilling fluids( also called mud ) in the drilling operation and protection for oil and gas, plays an irreplaceable role. But drilling fluids is mainly made of four parts: water, active solid phase, inert solid phase and chemical treating agent. Due to the various components of the ratio between and interaction, the related drilling fluids solids control equipment are necessary to adjust the mud performance to form different components and different performance of mud.
Jet mud mixer is an important solids control equipment to prepare and increase the drilling fluids weight by adding and mixing bentonite, change the fluid density, change the mud density, viscosity, and dehydration. The effect is more prominent matching with shear pump. Jet mud mixer is a unit used together with the solids control system for petroleum drilling and horizontal directional drilling ( HDD ). The unit includes one sand pump, one jet mixing hopper and one jet mixer that are installed at a base with pipe valves. It is safe and stable and can be moved conveniently.
Jet mud mixer matched with well drilling solids control, mainly used in weighting drilling mud, change the density, viscosity, water lose, etc. If it is used with shear pump, the effect will be more excellent, it can be designed as the twin jet mud mixer according to customers’ requirements .
The drilling fluids flows into the jet pump with certain pressure, in the jet pump, fluid spouts out from jet nozzle first, then flows into shear pipe through mixing chamber. Material will be added from hopper to mixing hopper, and move into shear pipe with the flow. During this process, they are dispersed and mixed. The mixture will enter into drilling fluids mud tank when flowing out of the shear pipe.
The shear pipe is hollow and it can expand gradually based on certain curved surface. It is mainly used to enlarge shearing force inside the pipe to disperse the material further and increase the mixture pressure head, this will make it easy to enter circulation tank.
